I don't think a single 512 MB DIMM counts as a "funny memory
combination", do you?

Sounds familiar. I've had two panics and two compile errors.

Not easily. That's the only DDR RAM DIMM I own, and this machine
takes nothing but.
When I get some time to do so, I'm going to take the machine down
and run memtest86. If it shows anything curious, I'm simply going to
return the DIMM I've got.
If not, is it possible that we've recently introduced a bug with
addressing "large" (because it's not, really) quantities of RAM? I'm

some way, but I don't think so. (Could I be seeing this behavior if
memory management syscalls had changed subtly and I had a libc that
didn't know about it?) I've still got 1.6D and 1.6B kernels I could
fall back to.
